I really hope this Palm Pre does well. I would have higher hopes for it if it didn't have carrier lock-in. We'll see if this Sprint-only deal lasts long or if it goes carrier neutral soon.
I've been spoiled by the web and I don't like having to deal with multiple languages, platforms and dev environments just to be able to reach a decent portion of my potential audience.
The videos I've seen of it make it look pretty second-rate. It probably compares well against other smart phones but it doesn't seem like a "real" competitor to the iphone. A JS/HTML SDK might be nice but it's not as deep and powerful as the iPhone's.
This is why I use MetroPCS. It's not the world's best service and it only works in major cities, but I pay $50/mo for unlimited voice/text and I have no contract. If you want the blackberry I think the unlimited data plan is about $75.
So, if you don't like contracts, pick T-Mobile; they're the closest thing to Europe available in the US.
Having said that, the Palm Pre is unreleased and many questions are still to be answered; especially delicate are those related to battery and performance ("the snappy"). It also seems a bit fat.
